Small height fluctuations were artificially introduced to the thin film samples by mechanically rubbing the sample surface with a rayon cloth before dewetting initiates. By comparing the dewetting morphology evolution and the characteristic length of dewetting structures of unrubbed and rubbed samples, the results clearly show that the dewetting mechanism for thinner polystyrene films with h≤13. 3nm is spinodal dewetting and that for thicker films with h≥13. 3nm is heterogeneous nucleation dewetting.

The intensity ratio of TO and LO inMCT was observed to be different. Such difference was explained in terms of the different Ramangeometry arrangement.〓. The laser-induced micro-photoluminescence in the range of 1000～5000〓(1.34eV～1.83eV) was found for the first time in LPE MCT epilayer. The center of photoluminescence wasat 2750〓 or 1.62eV and the FWHM of luminescence was 2000〓 or 0.25eV. We assume thatthe photoluminescence is due to recombination of electron from an anion vacancy resonance levelto the top of valance. In addition, new Raman shift was observed at 750〓 in LPE MCTepitaxial film.〓. The laser-induced micro-photoluminescence with quasi-periodic structure was observed forthe first time at room temperature in one of MOVPE MCT epitaxial film samples. The range offluorescence was from 1.46eV to 2.21eV, i.e., 1.73eV above the conduction band edge.

The crystalline defects of metallic substrate can promote the formation of multi-crystal thin films. In contrast, the films on the Si single crystal are basically amorphous; The hardness of films are mainly determined by N concentration. The highest hardnesses of Si〓N〓 and TiN films ware obtained at 1. 1 of N/Si and 0.96 of N/Ti respectively. The hardness of Si〓N〓 film decreased dramatically when the free silicon atoms present.

发现薄膜中N原子百分含量主要受氮离子束流和氮气分压的控制，随着氮离子束流和氮气分压的提高，N/Si和N/Ti原子比增加；膜的组织结构则主要受轰击离子束压和基体种类的影响，高的轰击束压可以抑制薄膜的择优取向，金属基体上的晶体缺陷使薄膜易于形成多晶，而单晶硅上的薄膜基本上为非晶态；薄膜的硬度受氮含量的影响最大。

The results showed that with the increase of nitride partial pressure in the range of 2. 0～8. 0×10〓Pa, the hardness of NbN, TaN single layer films decreased, but the hardness of TiN films kept unchanged.

The crystal structure of TiN films is FCC in all the range of partial pressure researched.
